The content explains a tool called "Empty Enter Expander," designed for the zsh shell (with a bash version in development), that allows users to quickly insert commands by pressing Enter on an empty prompt. The commands are stored in a designated module directory using files and folders that start with lowercase letters as shortcuts. Users can create and store their own commands in this directory, and to utilize the expander, they need to prepare a script for lengthy commands and save it under specific subdirectories with appropriately named

The content emphasizes the importance of user feedback and invites readers to consult the documentation for available qualifiers. It introduces the original source code of "Colossal Cave Adventure," a pioneering text adventure game from 1976, written in Fortran. The repository includes additional resources like maps, walkthroughs, and executables for Windows and Mac OS. The author discovered the game through the TV series "Halt & Catch Fire" and compiled the resources for educational purposes only.

The authors from the University of California, Berkeley have developed the Berkeley Humanoid Lite, an open-source humanoid robot aimed at promoting accessibility and customization in humanoid robotics. This initiative addresses the high costs and closed-source nature of existing robotic hardware, which limits community engagement and innovation. The robot features a modular 3D-printed gearbox and components that are easily sourced and fabricated, keeping total hardware costs below $5,000. The design uses cycloidal gears to enhance strength and durability over standard

The article from The Fence magazine reflects on the book series "Crap Towns," which the author began editing around the year 2000. "Crap Towns" surveys the worst places in the UK based on public nominations, alongside research and humorous commentary. The series aimed to portray the true state of the nation, described by critics as a “domesday book of misery.” The author appreciates that Adam Steiner interpreted "Crap Towns" as an affectionate critique, sparking discussions about

In 2025, a user is frustrated that their 24 CPU cores are underutilized during the configuration of a software build, with only 69% of one core being used, leading to a configuration time 13.5 times longer than the actual build. The ./configure scripts, typically used for checking the existence of various software components, are inherently sequential and do not take advantage of parallel processing, which is possible given the nature of these tasks. The author suggests using a configuration makefile

The author has created a "neural world" based on a forest trail near their apartment, accessible through a web browser. This world is generated by a neural network that creates new images based on previous ones and user controls without traditional coding elements like geometry or lighting. The key innovation is that the world operates locally and can be explored offline. The purpose of this project was to improve upon a previous effort where the author developed a 2D video game world using neural networks. Unlike video games that can

The Be File System (BFS) was created in the late '90s for the BeOS, Haiku, and SkyOS operating systems by Dominic Giampaolo and Cyril Meurillon. Its innovative features appealed to OS enthusiasts and included support for multi-threading, multimedia, and database capabilities, all while being lightweight. Despite Be's closure in 2002, BFS continued as an open-source project, re-implemented by Axel Dörfler for Haiku. This article delves

React Server Components feature two primary directives: 'use client' and 'use server', which facilitate communication between the server and client in a streamlined manner. These directives allow developers to model a client/server application as a cohesive unit spanning two machines, addressing complexities in network communication and serialization. The article claims these directives are as significant as foundational programming concepts like structured programming and async/await, potentially extending beyond React itself. The 'use server' directive enables backend API functionality, attempting to minimize the typical issues associated

The feedback received from users is valued and considered carefully. The importance of visualization in understanding asynchronous execution is highlighted, particularly for learners who grasp concepts better through practical experience. The document outlines a process to visualize async execution by rendering sine waves, demonstrating how futures compute values concurrently. The visualization involves creating asynchronous futures that calculate sine values, yielding execution to allow for parallel computation. The results initially depict two sine waves but are enhanced by incorporating execution duration, illustrating how the runtime processes each future. The commentary suggests that

The Cloud Native Computing Foundation (CNCF) invites companies to enroll as End Users, allowing them to save over $10,000 on training and conference costs. The CNCF emphasizes its role in maintaining open source principles, such as collaboration and neutral governance. However, these values are currently at risk due to Synadia’s intention to withdraw the NATS project from the CNCF and relicense it under the Business Source License (BUSL), which restricts user freedoms. This move is seen as

The author encountered an unexpected issue while writing a technical post about DNS resolution on Substack. Every time they typed the path to the hosts file (/etc/h*sts), their editor displayed a "Network Error" and failed to autosave the draft. Initial assumptions of a Substack outage were dispelled as the status page indicated all systems were operational. The problem was linked specifically to that file path, while variations like /etc/h0sts worked fine. Further testing revealed that paths to common Linux system

Code reviews in software development often face delays due to several common issues. Key factors contributing to slow reviews include misidentified ownership, poor communication, and a lack of incentives for developers to prioritize the review process. The total time for a code review spans from the request to approval, and bottlenecks frequently arise, especially in inter-team reviews. Many challenges are linked to cultural and social dynamics within the engineering environment. Developers often prioritize their own work over reviewing others' code when no performance incentives exist for

The content discusses how to work with flash messages in a Rails application, emphasizing their role in providing transient notifications to users. Flash messages can be informative or serve as warnings and are managed via ActionDispatch::Flash, which allows temporary data to be passed between actions. The text highlights that Rails does not automatically render flash messages, so developers must implement this themselves. It explains the difference between using `flash` (persistent until the next request) and `flash.now` (only available for the current request)

The article discusses implementing a QuadTree in TypeScript, highlighting its significance as a simple yet effective data structure utilized in fields such as computer graphics, compression, and game development. QuadTrees are particularly useful for efficiently locating nearby objects in a 2D environment, addressing the inefficiencies of a brute-force approach (O(n²) comparisons) when checking for collisions in games. A QuadTree organizes space by dividing it into four equal subregions—NorthWest, NorthEast, SouthWest, and
